Management of Idiopathic Gingival Enlargement.

Abstract

A 25-year-old male reported to the department with a chief complaint of swollen gums since 10 years involving all the teeth. The swelling was aesthetically unpleasing and also causing difficulty in speech and mastication. Patient did not undergo any kind of dental treatment for the above problem. Patients dental, personal, medical, family histories were non-contributory. Patient was not under any anti-epileptic, anti-hypertensive, immunosuppressive medication and there was no history of fever, anorexia, weight loss, seizures, hearing loss or any physical or mental disorder. On extraoral examination the patient has incompetent lips with convex facial profile. Intraoral examination revealed generalized diffused nodular enlargement of gingiva on both buccal and lingual/palatal sides [Table/Fig-1,​,22 and ​and3].3]. Gingival enlargement score of grade III (Bokencamp 1994) [1] was given, that is enlargement covers three quarters or more of the crown. Gingiva was pink in colour with superimposed melanin pigmentation, firm and fibrous fibrous in consistency. The teeth were barely visible as enlargement extended up to incisal/occlusal third of all the teeth except 11, 21, 13 and 23. Stippling was absent and slight bleeding on probing was present with altered gingival contour. Gingival enlargement was not superimposed by any secondary inflammatory changes.

Haematological investigation was done which was within normal limits. Histopathological examination revealed hyperparakeratinized stratified squamous epithelium showing pseudoepitheliomatous hyperplasia with thin elongated interconnecting retepegs [Table/Fig-5]. The underlying connective tissue showed extensive collagen consisting of coarse collagen fibres arranged in irregular fascicles [Table/Fig-6]. The fibroblasts were few with compressed blood vessels and scanty chronic inflammatory cell infiltrate. These findings were suggestive of fibrotic gingival enlargement. [Table/Fig-4]: Panoramic view.

On the basis of detailed case history and histological findings, the case was diagnosed as generalized idiopathic gingival enlargement. A treatment plan was devised for the patient Which included phase I therapy, followed by maintenance phase and phase II therapy. Adjunctive antimicrobial administration of systemic amoxicillin 500mg thrice daily and metronidazole 400mg twice daily for seven days was prescribed along with use of chlorhexidine mouthwash twice daily. The surgical phase included quadrant wise full mouth gingivectomy. Kirkl and knife was used for incisions on facial and lingual surfaces and Orban knife for interdental incisions [Table/Fig-7]. All granulation tissue was completely curetted and calculus remnants if any were scaled to make the areas clean [Table/Fig-8]. Patient was recalled after one month [Table/Fig-9] and two months [Table/Fig-10,​,1111 and ​and12].12]. Healing was satisfactory. [Table/Fig-7]: Gingivectomy done with Kirkland knife.
